Abstract
The toothbrush has a triple cross array of tufts of bristles. The tufts are disposed in rows which are disposed on a diagonal relative to longitude and axis of the toothbrush. In addition, alternating rows of the tufts have the tufts inclined at an acute angle to the base of the toothbrush and in crisscrossing relation to the tufts of the adjacent row.
Description
- This invention relates to a toothbrush. More particularly, this invention relates to a bristle arrangement for the head of a toothbrush.
- As is known, various types of toothbrushes and attachments for electric toothbrushes have been provided with arrays of tufts of bristles to accomplish the cleaning of teeth. In some cases, the tufts of bristles have been skewed at an angle to the more conventional perpendicular relationship to the head of a toothbrush. Skewing of the tufts has been intended to facilitate the cleaning of debris from the spaces between the teeth of a user.
- It is an object of this invention to provide an array of tufts for a toothbrush head that will efficiently clean the teeth of a user.
- It is another object of the invention to provide a toothbrush for efficiently cleaning the teeth of a user.
- It is another object of the invention to provide a toothbrush that is comfortable for a user to use.
- Briefly, the invention provides a head for a toothbrush that has a triple cross array of tufts of bristles. In particular, the invention provides a head for a toothbrush comprised of a body having an elongated shape along a longitudinal axis and a plurality of rows of tufts of bristles mounted on the body with at least some of these rows being disposed at an acute angle to the longitudinal axis of the body. In addition, the tufts in these rows are disposed at an acute angle to the plane of the body as well as in criss-crossing relation to the tufts in an adjacent row.
- In one embodiment, the triple cross arrangement of tufts is used on a conventional toothbrush having a body of elongated shape along a longitudinal axis of the toothbrush. The rows of tufts are mounted on the head of the body with the rows being disposed at an acute angle, for example of 27°, to the longitudinal axis of the body. In addition, the tufts in each of the rows is disposed at an acute angle, for example of 18°, to the plane of the body and in criss-crossing relation to the tufts in an adjacent row.
- In addition, a retainer wall is mounted on the body of the toothbrush and is located at the rear-most tuft at the end of each row of tufts for restraining the bristles of the rear-most tuft from deforming during use. This retainer wall may be made of plastic suitable for use on the toothbrush and is typically one-half the height of the adjacent tuft and slightly wider than the tuft in order to protect the bristles of the tuft from being permanently deformed due to pressures exerted during use.
- These and other objects and advantages of the invention would become more apparent from the following detailed description taken in conjunction with the accompanying drawings wherein:
